VS Code extension

Looking through the history, was almost six years ago, and in the mean time the need for a real JSON5 extension for VS Code has only become more important, not less =)

Even if you don't want to do the work yourself, consider just contacting the "better json5" dev and giving them a json5/vscode-json5 repo to work in, with some support so they can add in the features that are still missing.
